On October 8, 2026, we released an update improving some systems and addressing some in-game issues.
Please check that the version number in the lower right corner of the main menu is displayed as v1.5.154194.
System Changes
・Gameplay & AI Improvements for The Weight:
- Grab attacks now deal heavy damage instead of causing instant death on Story Mode and Normal difficulties.
- Searching behaviors have been improved to prevent The Weight from ‘camping’ in front of the player’s objective for long periods of time.
- Searching behaviors have been improved to prevent The Weight from repeatedly searching the same location and remaining there for long periods of time.
- Hunting behaviors have been improved to prevent The Weight from tracking the player too aggressively.
・Gameplay & AI Improvements for enemies:
- Enemy sensitivity to the sound of firearms has been reduced.
- Enemy sensitivity to the sound of the player while running has been reduced.
- Enemy sensitivity to the sound of the player entering a hiding space has been reduced.
- The frequency of enemy counterattacks after successful player attacks during melee combat has been reduced.
- With the exception of The Weight, grapple attempts from enemies while the player is actively blocking with a melee weapon have been removed.
- Players are now given more time to react to enemies after escaping a grapple.
・Puzzle Information Design Improvements
- A collectible manual for the "Remote Systems Control" console that can be viewed for quick reference while operating the console has been added.
- The pipe layout for the "Aux Line" puzzle has been updated to improve clarity.
